Specification of Letters Patent.

Application filed August 29, 1914. Serial No. 859,146.

T0 all Lelio/m, it may concern.'

Be itknown that we, GEORGE H. BAUGi-I- MAN and FRANK J. Smruwmr, bothcitizens of the United States, and residents of Chicago, in the countyof Cook and State of Illinois, have invented certain new and usefulImprovements in Clamps for Sales-Book Pads, of which the following is afull, clear, and exact specification.

Our invention relates to what' are commercial'ly known as sales-books,that is binders for suitably and conveniently holding a pad of saleschecks, sales tickets or the like such as are usually employed inmercantile establishments for memoranda of purchases made by customers.The pages or tickets of theselpads are adapted to be torn-out by thesales person making the sale and when a pad has been entirely used thestud thereof is adapted to be replaced by anotherpad which is insertedbetween the covers of the said-book after the said stub has beenremoved.

More particularly7 our invention pertains to the devices for removablyvclamping and holding the pad between the binding covers of the bookmember and its particular object Vis the provision of a clamp that iseasy for the sales person to manipulate when removing or replacing apad.

Another object is to construct a clamp of the type mentioned that willsecurely and firmly hold the pad when the latter is placed between itsclamping jaws. A still further object is the provision of a clamp thatis inexpensive to manufacture so that it will not materially add to theretail cost of the sales book.

These and other objects we prefer to accomplish by the means and in themanner hereinafter fully described and as more particularly pointedoutin the claims, reference being had to the accompanying drawings forminga part of this specification wherein similar reference characters.indicate the same parts in the various figures.

In the drawings z-Figure 1 is a perspective view. partlyfragmentary, ofa salesbook in opened position showing our invention applied thereto andgripping a pad of sales checks.V Fig. :2 is a rear elevation of theclamping members, detached from the book and in their respectivepositions for clamping a pad. Fig. 3 is a view similar to Fig. 2 butshowing the clamping members opened. Fig. -L is a transverse verticalsection of the book taken on the line 4.-1 of Fig. 1.

YI'4`or the purpose cfu-convenience in describing our invention we haveherein illustrated and described the same embodied in a. Sales-book, butit of course will be obvious to others skilled in the art to which itrelates that the principles involved may be readily applied withoutalteration or change to binders for j loose-leaf ledgers, transferbooks,files and the like. 'e therefore desire it understood that such uses andapplications are contemplated by us. l

Referring to the drawings A and B rep,- resent respectively the top andbottom covers -of a sales-book that are usually constructed ofrelatively stift' material and are hinged or connected together by meansof 'a suitableV flexible back portion C, substantially as shown in Figs.1 and -l of the drawings. Seeured upon the inside surface of cover B anddisposed in a transverse plane substantially parallel with the back edgethereof is the stationary clamping jaw' or member 5 of the clamp. Thisstationary jaw 5 preferably comprises an elongated strip of angularsheet metal, substantially L- Patented Oct. 19, 1915.

shaped in 4cross-section that is so arranged that one of its members isdisposed at a right angle to s aid cover and projects upwardlytherefrom, while its opposite member, which is slightly upturned orflared as at 6 along its outer edge, is preferably secured to said coverby lneans of rivets 7 or in any other suitablemanner. The coperating ormovable clamping jaw S is likewise preferably constructed of angularsheet metal of a substantially L-shape. as shown and is inverted ordisposed so that its vertical member lies fiat against. and, as willhereinafter be described, is adapted to be clamped to the verticalupstanding portion of the lower or stationary jaw- The horizontalmelnber of jaw S preferably slopes or is inclined slightly downwardlytoward the adjacent cover B and its outer free edge is inturned orflared as at 9. AWhile it is not considered essential we desire toconstruct these clamping jaws so that one of their. flared edges(preferably the upper edge) lique or inclined slot 10 in the vertical orupright member otl jaw 5 and to cut. an oppositely inclined longitudinalslot 11 in the .corresponding vertieal member of jaw S. These slotsrenter of length of said jaws that portions of said slots'will beopposite and register with each other, and at the point ot' registry orintersection we insert a flattened sei-ew. bolt or similar element 12-transversely through them so that it will extend beyond the verticalplane of the outer surface ot' the clamping jaws. Bolt 12 is providedwith an enlargement or head 13 upon its inner end and a knurled thumbnut 14 or the like is screwed onto its outerextended end for the purposeof locking the parts together. '1f desired, after the nut 14 has beenplaced upon the bolt 12 the outer end of the latter may be swayed overto prevent the accidental removal of the nut.

In operation, when it is desired to open the clamping jaws the nut isloosened and bolt 12'is moved toward the position shown in Fig. 3 whichwill cause the bolt to travel upwardly in slot 10 and downwardly in slot11 until the ends of the slots are opposite each other in which positionthe jaws will have been separated to their full extent. The edge of apad of sales-checks D may then be inserted between the jaws, after whichthe bolt 12 is adapted to be moved bodily in a. reverse direction untilthe same,

.acting as a wedge in oppositely inclined slots 10 and 11, will causethe approx1ma tion of the respective jaws and will securely clamp thepad, whereupon the nut 14 may be turned down on the bolt to securelylock the parts together. guide the movable jaw and prevent longitudinalmovement of the same, we prefer to turn back the opposite end edges 15of the vertical member of stationary jaw 5 to form i suitable gnidewaysin which the adjacent end edges ot' said movable jaw are adapted totravel and thereby retain the lat-ter in parallel relation.

lWhile we have illustrated and described certain specificinstrumentalit-ies for carrying out our invention it of course will beobvious to others skilled in the art to which it relates that variouschanges and modifications may be made Without materially departing fromthe spirit thereof. We wish it understood therefore that suchrefinements are included within the. scope of our inven tion asexpressed in the appended claims.
